Experiment 13: Calcium Carbonate Analysis; Molar Volume of Carbon Dioxide
Abstract: The goal of this experiment was to determine the percent calcium carbonate in a heterogeneous mixture and to determine the molar volume of carbon dioxide gas at 273 K and 760 torr. This is done by constructing a gas generator to collect the CO2 gas evolved from the reaction. The masses of the sample in the gas generator before and after the reaction are measured. The volume of CO2 gas is also collected and measured. As a result, we found that 25L of CO2 was collected, and after further calculations the molar volume turned out to be 13.28L which is very close to the estimated 22.4 L at STP.

I am going to talk today about whether Australia should support a carbon tax, in which I will argue for the implementation of the tax in our law.
A carbon tax; a form of carbon pricing, taxes the amount of carbon burnt that is present in fossil fuels, such as coal and natural gas by environmental carbon dioxide polluters.
The purpose of a carbon tax is that it is used as a financial disincentive towards Australian businesses who emit carbon dioxide into the Earth's atmosphere. A carbon tax will require these polluters to pay a charged legal fee based on the amount of carbon dioxide that they release from burnt fossil fuels into the atmosphere.

Cause and effect of global warmingGlobal warming occurs when the levels of greenhouse gasses rise and less infrared light, or heat, escapes the earth's atmosphere. Thus, the temperature experienced on Earth begins to rise. Climate change is a part of the Earth's history. There have been dramatic fluctuations in overall average temperature for the past 150,000 years that suggest a direct association with carbon dioxide levels.In the past the temperature highs and lows have been in tandem with carbon dioxide level highs and lows, this does not seem to be a mere coincidence. Carbon dioxide currently accounts for 0.03% of the gas content within the atmosphere. However, it has a disproportionate

Global warming can be described as the increase in the average temperature of Earth’s atmosphere, oceans and landmasses caused part by the greenhouse effect. The planet`s temperature continues to rise due to the rise of the greenhouse gases in the atmosphere. Greenhouse gases retain the radiant energy (heat) provided to earth by the sun in a process known as the greenhouse effect. Greenhouse gases occur naturally and without them the planet would be too cold to sustain life as we know it. Carbon dioxide, a powerful greenhouse gas has risen by 35% since 1750, largely from the burning of fossil fuels such as coal, oil, and natural gas and because of the increase of gases such

The long-term objective of the Convention expressed in Article 2, is that the concentrations of greenhouse gases in the atmosphere should be stabilized ‘at a level which would prevent dangerous anthropogenic interference with the climate system’ (Krasno, 2004, p.13). This stabilization should be achieved within a time-frame sufficient to allow ecosystems to adapt naturally to climate change so that food production is not threatened. In addition, it will enable economic development to proceed in a

Plants are very important to all life forms on earth. They help provide the vital source of oxygen that is required to sustain life. But how do plants provide oxygen? What do they do with carbon dioxide? Animals not only get the benefits of oxygen from plants, they also get nutrients by eating them. Without plants, all life forms that require oxygen would be non-existent.
Plants release oxygen through a process called photosynthesis. Photosynthesis needs three things in order to start this process. They are carbon dioxide, water and sunlight. Carbon dioxide is taken from the atmosphere and then passes through the stomata and into the air spaces of the spongy mesophyll cells

Cellular respiration is a chemical reaction that involves the breakdown of glucose to provide ATP energy for the cell (Rogers, 2010, October 12). This process occurs in mitochondria between blood and the air in alveoli. The waste products of cellular respiration are carbon dioxide and water. Carbon dioxide is a gas that is released from the cells during exhalation. In order to determine the effects of exercise on the rate of cellular respiration, breathing rate, heart rate, and carbon dioxide production will be measured at rest and after 1 and two minutes of exercise. Breathing rate is measured in breaths per minute, heart rate in beats

Smog hanging over cities is the most familiar and obvious form of air pollution. But there are different kinds of pollution, some visible and some invisible, that contribute to global warming. Generally any substance that people introduce into the atmosphere that has damaging effects on living things and the environment is considered air pollution.
Carbon dioxide, a greenhouse gas, is the main pollutant that is warming Earth. Though living things emit carbon dioxide when they breathe, carbon dioxide is widely considered to be a pollutant when associated with cars, planes, power plants, and other human activities that involve the burning of fossil fuels such as gasoline and

With that being said we can beginPlant cells retain chloroplasts. These functions within the plant cells use a compound named chlorophyll to obtain energy through the sun and combine with water and carbon dioxide to fabricate glucose (type of sugar) and oxygen. The chemical equation describing this effect, photosynthesis is written this way: 6CO2+6H2O+energy →6O2+C6H12O6.

Topic – Describe the importance of photosynthesis to life on earth.
The formula for all life on earth is 6 CO2 + 6 H2O + photons → C6H12O6 + 6 O2. Without this formula, life as we know it, would not exist. Simply, six carbon dioxides plus six waters plus sunlight gives off a simple sugar plus six oxygen molecules. Photosynthesis is the very basic building block for the earth's food supply. Without this simple chemical reaction you, me and everything we know would cease to exist. Let us explore the world of photosynthesis.

Sulfuric acid is the major cause of the acidity of acid rain, which not only damages the forests in the Northern Hemisphere, but is also causes fish to die off in many northern lakes. Solutions for this problem are very expensive; due to the difficulty of removing the sulfur from coal and oil, they are burned. Carbon dioxide is less lethal than carbon monoxide, sulfur oxide, and nitrogen oxide, but carbon dioxide (CO2) is the one major pollutant in the atmosphere.

Fossil fuels include common sources of energy such as coal and natural gas. These fuel sources developed thousands--sometimes millions--of years ago, depending upon the type. The energy output varies with the material, with peat producing the least amount of energy and the lowest amount of carbon. The pollution resulting from fossil fuels is caused by the toxic emissions they release. Fossil fuel combustion releases carbon dioxide, nitrogen oxide, methane and other emissions in the air. Although some of these chemicals are naturally occurring, the high concentrations cause pollution and its effects.

The Effect of Light on Photosynthesis
Plants need and use the same light of foods as animals but while
animals have to eat other things to get their food, plants make it
themselves. The way they do this is called photosynthesis. The other
ways that plants are different from animals, such as having leaves and
root or being green, they are all linked with photosynthesis. In
photosynthesis, plants take carbon dioxide from the air and water from
the soil, and use the energy from the sunlight to convert them into
food. The first food they make is glucose but that can later be
changed into other food types. The sunlight is absorbed by the green

Homeostatic is carried out around the whole body, it reaches from every cell up to whole organs and systems. We need the homeostasis because if there was no constant internal environment, our enzymes would not work properly. It means that nothing would operate correctly and we would then die. There are six things that are essential to health and which must be controlled: carbon dioxide, urea, ions, sugar, water and temperature. We need to remove waste products from the body to keep it working, as waste products can be poisonous to the body. If they are not removed then it can stop chemical reactions from happening and cells can be damaged.

Carbon dioxide is one of the main causes of global warming. This is because of its heat trapping abilities (Global Warming). Carbon dioxide is produced; when animals, plants, and bacteria breathe, by the natural decay of organic matter, by volcanic activity, and when any material containing carbon dioxide is burned (includes oil, coal, natural gas, or wood) (Global warming - just facts).

It is true that Global warming is caused by the ozone layer slowly depleting and making Earth’s conditions warmer, but the Greenhouse Effect is mainly caused by a layer of gases under the Earth’s atmosphere. These gases, known as the Greenhouse Gases are made up of many gases such as water vapor, carbon dioxide, methane, nitrous oxide, ozone, and chlorofluorocarbons (CFCs).

Evidence shows that global temperatures have been rising steadily over the last few decades (Nodvin, 2010), and that this has had an effect on the natural climate and topology of our world. Global warming is a result of the greenhouse effect. Our earth is naturally surrounded by a layer of insulating greenhouse gases which help to retain energy within the earths’ atmosphere. Increase in the levels of greenhouse gases - such as carbon dioxide (CO2), water vapour and methane - results in an increase of the heat trapped, boosting the global temperature.

In the time since the Industrial Revolution, the carbon dioxide content of the atmosphere has changed dramatically which strongly suggests the human emissions are to blame. Prior to the Industrial Revolution in the 1700s, the carbon dioxide content in the atmosphere was about 280 ppmv (parts per million by volume) and has since then raised to 360 ppmv which is a dramatic increase of nearly thirty percent and averaging an annual increase of 1.5 ppmv (Houghton, 1997). This is a dramatic increase in such a relatively short period of time. Given how dramatically the carbon dioxide levels in the atmosphere have increased in such a short amount of time, this strongly suggests that the
